The project aims for simple implementation, massive scalability, and a rich set of features. Cloud computing experts from around the world contribute to the project. OpenStack provides an Infrastructure-as-a-Service (IaaS) solution through a variety of complemental services. Each service offers an application programming interface (API) that facilitates this integration. This guide describes how to deploy these services in a functional test environment and, by example, teaches you how to build a production environment.

Launching a virtual machine or instance involves many interactions among several services. Figure 1.1. OpenStack is highly configurable to meet different needs with various compute, networking, and storage options. Three-node architecture with OpenStack Networking (neutron).
Build a cloud. Official Ubuntu Documentation. Scope of this documentation This document provides instructions on how to install the Metal As A Service (MAAS) software.

It has been prepared alongside guides for installing Juju, OpenStack and Landscape as part of a production grade cloud environment. MAAS itself may be used in different ways and you can find documentation for this on the main MAAS website [MAAS docs]. For the purposes of this documentation, the following assumptions have been made: You have sufficient, appropriate node hardware You will be using Juju to assign workloads to MAASYou will be configuring the cluster network to be controlled entirely by MAAS (i.e. Introducing MAAS Metal as a Service – MAAS – lets you treat physical servers like virtual machines in the cloud.

What does that mean in practice?
Official Ubuntu Documentation. Introduction Juju is a powerful tool for managing scale out architectures in the cloud.

It bootstraps an instance in your cloud from where it can deploy, relate, manage and scale services in all directions. Running from the commandline or an intuitive GUI, it delivers on its promise to orchestrate services rather than simply deploy them In modern scale out architectures, servers are just units that enable application services to scale. Services are managed independently of the underlying hardware so you don’t need to worry about launching new instances and setting up config files to connect applications, Juju just takes care of it all. Other solutions focus on configuration management to enforce consistency across scale out architectures but Juju creates services as building blocks that are connected together simply by drawing a line between the two.

Official Ubuntu Documentation. Introduction OpenStack is a versatile, open source cloud environment equally suited to serving up public, private or hybrid clouds.

Canonical is a Platinum Member of the OpenStack foundation and has been involved with the OpenStack project since its inception; the software covered in this document has been developed with the intention of providing a streamlined way to deploy and manage OpenStack installations. Scope of this documentation The OpenStack platform is powerful and its uses diverse. This section of documentation is primarily concerned with deploying a 'standard' running OpenStack system using, but not limited to, Canonical components such as MAAS, Juju and Ubuntu.

Assumptions. Official Ubuntu Documentation. In order to keep your Ubuntu Cloud up to date and operating at its best, there are some common administration tasks you may wish to perform.

These are detailed here. Logging Logging is set up to occur on each instance. This includes the normal service logs for whichever services are deployed on that particular instance. For example, if you deploy the apache2 service, the logs will appear on that instance in /var/log/apache2/ as one might expect. Juju ssh <machine number> The same directory also contains the juju logs for that service, located in /var/log/juju. Connecting to rsyslogd The target of the aggregated log is the file /var/log/juju/all-machines.log.

Juju debug-log [-n <number>] [-n +<number>] [-e <environment>] Where the -n switch is given and followed by a number, the log will be tailed from that many lines in the past (i.e., those number of existing lines in the log will be included in the output, along with any subsequent output).
Official Ubuntu Documentation. About Landscape Landscape is a system management tool designed to let you easily manage multiple Ubuntu systems - up to 40,000 with a single Landscape instance.

From a single dashboard you can apply package updates and perform other administrative tasks on many machines. You can categorize machines by group and manage each group separately. You can make changes to targeted machines even when they are offline; the changes will be applied next time they start. Landscape lets you create scripts to automate routine work such as starting and stopping services and performing backups. Ubuntu Advantage Ubuntu Advantage comprises systems management tools, technical support, access to online resources and support engineers, training, and legal assurance to keep organizations on top of their Ubuntu server, desktop, and cloud deployments.
